Biography
Mithridates was born in Pergamon, the son of Mithridates VI of Pontus and Adobogiona the Elder; he was of Persian, Macedonian, and Celtic ancestry. He became a tetrarch of the Trocmi tribe, and Mithridates raised an army to assist Julius Caesar in his invasion of Egypt in 48 BC. Caesar had sent the call for help before he even landed in Egypt, knowing that he would be caught in the middle of the Alexandrine Civil War. Mithridates helped to lift the Egyptian Siege of Alexandria and fought at the Battle of the Nile, helping to crush Ptolemy XIII. After the Battle of Zela, Caesar had Mithridates become the new ruler of the Bosporan Kingdom, but Asander of the Bosporus regained power after Caesar's death in 44 BC. Mithridates abdicated, and he died soon after.
